About this service
Glow-worm Boilers in South West London, done properly the first time
Glow-worm sits under the Vaillant group, so it shares engineering and parts logic with the ecoTEC platform at a lower price point. For rental properties across KT1, KT2 and TW9 it is often the most sensible balance of cost and serviceability.
Whether you need a straight Glow-worm swap, a move from a regular boiler and cylinder to a Glow-worm combi, or a diagnosis on a unit that keeps locking out, the work is carried out by our own Gas Safe engineers — never sub-contracted. We survey the property first, because the right answer in a three-storey Victorian terrace in New Kingston upon Thames is rarely the right answer in a two-bed flat in Putney.
On Glow-worm boilers the faults we are called to most are F22 — low water pressure; F28 — failed ignition; F75 — pump or pressure sensor; F1 — flame loss. Most are repairable in a single visit once diagnosed properly, and we will always tell you plainly when a repair is not worth the money against a replacement.
Rental properties and budget-conscious replacements where parts support still matters. If you are weighing Glow-worm against another manufacturer, ask us — we install every major UK brand, so we have no reason to steer you anywhere except the boiler that suits your property, your hot water demand and your budget.

Frequently asked
Your questions, answered
Do you install Glow-worm boilers in Kingston upon Thames?
Yes. Our Gas Safe registered engineers install, service and repair Glow-worm boilers across Kingston upon Thames (KT1, KT2 and TW9) and the neighbouring TW11, KT3 and SW19 postcodes, as well as Richmond, Wimbledon, Twickenham, Surbiton, Fulham, Putney, Teddington, New Malden, Molesey, Hounslow, Brentford, Isleworth, Long Ditton, Worcester Park, Roehampton, Raynes Park, Morden, Petersham, Motspur Park and the rest of South West London.
Which Glow-worm models do you work on?
We work across the current Glow-worm range — including Energy Combi, Energy System, Betacom4, Ultimate3 — and we still service and repair older models where parts remain available.
How much does a Glow-worm boiler cost to install?
We do not publish prices for boiler work, because the honest figure depends on the model, the state of your existing system, flue and condensate routes, gas pipe sizing and access. Send us a few details or call and we will give you a fixed written price for your property before anything is booked.
What warranty comes with a new Glow-worm boiler?
Warranty length depends on the specific Glow-worm model, the installation and registering the boiler with the manufacturer, so we confirm the exact terms in writing with your quote rather than quoting a headline figure. Annual servicing is normally a condition of keeping any manufacturer warranty valid. Our own workmanship guarantee sits on top of it.
Can you repair a Glow-worm boiler that has locked out?
Usually, yes. The faults we see most often on Glow-worm are F22 — low water pressure; F28 — failed ignition; F75 — pump or pressure sensor. We diagnose first, tell you what the part and labour will be, and only then carry out the repair.
Which areas do you cover for Glow-worm boiler work?
We cover the whole of South West London for Glow-worm installation, servicing and repairs, including Kingston upon Thames, Richmond, Wimbledon, Twickenham, Surbiton, Fulham, Putney, Teddington, New Malden, Molesey, Hounslow, Brentford, Isleworth, Long Ditton, Worcester Park, Roehampton, Raynes Park, Morden, Petersham, Motspur Park and the surrounding KT, TW and SW postcodes.
